Iron is needed by the body to produce red blood cells. It’s a component of haemoglobin in red blood cells which carry’s oxygen around the body.
There are two different types of iron - Haem iron and non-haem iron. Haem iron is better absorbed by our bodies than non-haem iron. This absorbable iron is found in animal foods. One of the richest sources is liver, but it’s also found in beef, lamb and pork. Sources of non-haem iron include green leafy vegetables such as kale, egg yolk, dried fruit and fortified foods like breakfast cereals.
When it comes to iron deficiency anaemia, symptoms may come on suddenly, or may gradually build up over time. The most common symptoms are tiredness, shortness of breath, paleness and palpitations. Other symptoms include headaches, hair loss, tinnitus and mouth ulcers.
If iron deficiency anaemia is left untreated, it can affect your immune system, making you more susceptible to infection. Pregnant women with low levels of iron are also more at risk for complications during and after pregnancy, so it’s really important to monitor levels to ensure they’re in the right ranges.
There are a few things which can lead to iron deficiency. One of the most common cause in women is monthly blood loss from menstruation. Women are particularly at risk if they suffer from particularly long or heavy periods. Other causes include bleeding from stomach ulcers, bowel cancer or stomach cancer.
Iron deficiency anaemia is the most common type of anaemia but there are also other types such as pernicious anaemia which is caused by a deficiency in vitamin B12. Symptoms are similar to that of iron deficiency anaemia and include shortness of breath, fatigue and paleness.
